Abstract: A magnetic body (121) consists of a plurality of individual bodies (101) each of which is an individual magnet whose exposed base surface (103) is constructed as a north pole or as a south pole and whose other surfaces, which are covered by materials that are magnetically not present and by a separating material, screen the other pole. Since, for example, the south poles of all the individual magnet bodies (101) are located inside the main body (121), the totality of the region at a distance from the surface (103) of the main body (121) represents a north pole. If the north poles and south poles are interchanged, a magnet body having a monopolar surface representing a south pole can, of course, be produced. The supporting arrangement has radially magnetised ring magnets which are arranged one above the other axially in the shaft and, on the stator part, annular, likewise radially magnetised, magnets which are opposite the magnets and consist of a large number of assembled other surfaces which, with the exception of the "effective" surface are, however, screened by a separating material.
